Downloadable ACL
The downloadable ACL (DACL) feature allows you to download device specific authorization policies
from the authentication server. These policies activate after authentication succeeds for the respective
client and the client's IP address was populated in the IP device tracking table. (Downloadable ACL is
applied on the port, once the port is authenticated and the IP device tracking table has the host IP address
entry).
The following sections describe the configuration that is necessary to complement the related
authentication (802.1X or MAB) configuration. (No unique configuration is required on the switch. All
of the configuration is on the ACS.) After authentication succeeds, enter the show ip access-list
command to display the downloadable ACLs.
Configuring the Switch for Downloadable ACL
To configure the switch for downloadable ACL, follow these steps:
Step 1 Configure the IP device tracking table.
Switch(config)# ip device tracking
Step 2 Configure RADIUS VSA to forward authentication.
Switch(config)# radius-server vsa send authentication
Configure static ACL for the interface.
Step 3
Switch(config)# int g2/9
Switch(config-if)# ip access-group pacl-4 in
